Not with the Cumulus UI because the built-in MX 'web server' is lightweight and doesn't do PHP. You would need to run a proper web server on the Pi and run the standard web site (or part of it) on that, for viewing locally.

It doesn't look like you have loaded the .htaccess file on your web server?
You can only access the files via their full filenames eg "graphPress.php", whereas the gauges script is looking the aliases eg "press.png"

It passes PHP and jpgraph testing, but no graph is showing up in the pop up.

Here is a pic from the above referenced thread that shows what I get:

So, I am wondering .... might there be something in the php.ini that I need to do?

My second guess is that I didn't follow the wiki on changing from html to php - I just changed the Cumulus.ini file to upload the processed "T" files with a php extension. I am not permitted by my ISP to run a server so this is in house only and I can't provide any urls.
